ASP.NET Core MVC long running operation

Question

I have an ASP.NET Core application that executes a query based on user requested tokens, and is accessing external systems authenticated as the user. This request takes a long time to complete, and I want to make it asynchronous. To be able to do that I was looking into using a background service to offload the work, and to use SignalR to respond to data received events, however I can't find a good way to execute a long running task 'as a user' from an MVC controller action.

What is the preferred / best way to do this? Or am I missing something?

Answer 1

看一下托管服务 ，如果您想自己实现所有功能，这是aspnet执行长时间运行任务的核心方法，否则我也建议使用Hangfire

Answer 2

Yes, I will suggest using the Hangfire as it enables to schedule tasks with a Cron expression. Cron expression will allow you to set tasks with long intervals which can give sufficient time to complete long time tasks.
